8 Mr. H. J. Elvves' additiunal notes 



Fieldii and Eogene are ever found flying together, but am 

 not aware that this is so ; Fieldii inhabiting'the warmer 

 damper region of the Lower Himalaya, whilst Eogene 

 seems to be confined to the dry barren region of Ladak, 

 which is beyond the influence of the rains. The basal 

 patch in Fieldii (male) appears constantly present though 

 variable in extent and colour, and Alpheraky agrees with 

 me in considering it a distinct species. 



PS. — I have just received a valuable note on this spe- 

 cies from Capt. Graham Young, whose local knowledge 

 of the butterflies of the N.W. Himalaya is very extensive. 

 He says — " This insect is very common in the Sialkot 

 district in early spring, at about 900 feet elevation. I 

 have taken it as high up as 14,800 feet on the top of the 

 Humpta Pass, in Kulu, in September, when it was the 

 only butterfly to be seen. In Kulu, at 3500 — 4000 feet, 

 it comes out the first week in April, and swarms in the 

 fields of vetches. It disaj^pears by the middle of May 

 from that zone of elevation, though a few may be seen 

 in autumn ; but comes out in profusion on the grassy 

 hihs from 6000—10,000 feet." 



In the Chumbi Valley, on the Tibetan frontier of 

 Sikkim, it is abundant at 10,000 — 12,000 feet in autumn, 

 and in Kashmir and Hazara it occurs from June to 

 August at 6000 — 10,000 feet. A few smaller paler speci- 

 mens occur among numbers of the usual type, but I do 

 not yet know that the spring and summer broods can be 

 distinguished apart ; and it seems somewhat doubtful if 

 successive broods do occur in the same district, or 

 whether the species may not rather be single-brooded, 

 appearing earlier or later according to the climate of the 

 locality. 



Colias Meadii, Edwards. 



Edwards, Butt. North Am., i., 6'oZ., pi. 8, fig. 6— 9, 1872 ; 

 Zeher, Stett. Ent. Zeit., vol. 35, p. 437 ; Hagen, Proc. 

 Boston Soc. Nat. Hist., 1882, p. 175. 



This species I formerly placed as a variety of Boothii, 

 but this was undoubtedly an error. Hagen considers 

 it most nearly allied to, but distinct from, Myrinidone, 

 and, with a good series of each form before me, I am 

 inclined to agree with him, though, as it appears to be 

 generally allowed that Chrysotheme in 'Europe and North 

 America are identical, it would be less extraordinary if 

 Meadii and Myrmidone should also represent the same 

 species in the two continents.
